Impedance of waveguide
Did you know?
A propagation mode in a waveguide is one solution of the wave equations, or, in other words, the form of the wave. Due to the constraints of the boundary conditions, there are only limited frequencies and forms for the wave function which can propagate in the waveguide. The lowest frequency in which a certain mode can propagate is the cutoff frequency of that mode. The mode with the lowest cutoff frequency is the fundamental mode of the waveguide, and its cutoff freque… WitrynaThe Wiener-Hopf technique is used to compute the reflection and transmission coefficients related to the junction of perfectly conducting and impedance parallel plate waveguides in the case where the surface impedances of the upper and lower semi infinite plates are different from each other.
